What is the best definition of an argumentative text?
a text that uses persuasive language to promote one point of view on an issue - this is not the correct answer on edge
a text that supports a claim about a debatable topic using evidence as support
a text that presents evidence to inform the audience about a specific topic
a text that uses rhetorical devices to support a particular perspective

The answer is: a text that supports a claim about a debatable topic using evidence as support.

The argumentative text is used claiming about a point of view, or debatable topics. People use argumentative text every time they want to prove something, claiming that it's true (or not) by using proper evidence.

For example, in a trial, the accusing lawyers use the arguments in order to convince the judge that the accused is guilty, they do that exposing evidence that can prove their point.

Have a nice day!
